What are the temperatures of the known phase transitions for

What are the temperatures of the known phase transitions for trans-stilbene, ammonium chloride, and p-azoxyanisole that fall in the temperature range 0-200 °C.

Solution

ans

The phase transition temperature is defined as the temperature required to induce a change from one phase to another phase

Phase transtition temperature of

Trans-stilbene is 124.4°C. (397.40 K)

Ammonium chloride 120°C (465 K)

p-azoxyanisole is 118 °C(391 K)
